Four months after their babies were swapped, workaholic Ana and student Mariana prepare to carry out the exchange. But what if they don't have to?

Mariana moves in with Ana and her family to wean Valentina. Tere, Mariana's mom, is surprised when Juan Carlos, Ana's husband, offers to help them.

Ana and Juan Carlos go to couples therapy. Pablo and Regina go on their first daddy-daughter date. Tere launches her beauty business.

Mariana and Pablo decide to get new jobs to make ends meet. Ana strikes a deal with her ex-boss. Ceci and Rodrigo go to a party to avoid their dad.

Mariana and Pablo are reluctant to put Regina in daycare. Tere partners up with Victor for a new business. Ana makes a career move that shocks Mariana.

Things get hectic when the two families end up in the same co-working space and Ferrán, the owner, starts flirting with Ana — and Mariana.

After Ferrán gets on Pablo and Juan Carlo's nerves, they meet with a lawyer. Mariana helps Ceci plan a romantic night with Dario, to Ana's dismay.

When Pablo and Juan Carlos take legal action against Ana and Mariana, the women resort to an extreme solution to protect their families and business.
